Dharma Productions' Brahmastra is going to give us a new talented trio on screen -- Amitabh Bachchan, Alia Bhatt and Ranbir Kapoor. The actors have started preparing for the film, the glimpse of which was shared by Big B himself on social media recently.

The three started to brainstorm on the script with director Ayan Mukherjee. And it seemed Mr Bachchan was totally in a jovial mood while doing so.

Senior Bachchan posted a series of three photos from the prep meet. The first photo said, "We prep for BRAHMASTRA...Ranveer, Alia , Ayan...every one else except me... I prep to brush my teeth." Check it out here:

The picture has everything alright about it. Except that Ranveer wasn't there.

The Piku actor actually made a typo mistake by writing Ranveer for Ranbir. But, he realised it soon and posted another picture of them. This time, with the right caption -- "We prep for BRAHMASTRA...RANBIR , Alia, Ayan ..all except moi...I seem to be having an outer space experience..."

The director also could not stay away from posting the selfie 'clicked by legendary Amitabh Bachchan'.

Even at 75, Mr Bachchan's enthusiasm is on point. He recently bagged the first position on the Facebook's chart of most engaging actors, which was surveyed and acknowledged by Score Trends India.

The 102 Not Out star is said to have a cameo in Brahmastra. This is, for the first time, that Alia and Ayan are working with Big B. As for Ranbir, he has worked with the legendary actor in Bhoothnath Returns (2014) for a cameo appearance.
